I have got the software somewhere, its on a floppy disk and runs in DOS!!!!!! I am in North Wales so its a long way to Stealth.I have a really old laptop that I used to use in the car when I was playing with the setup, probably will dig it out and see if it still works, you also need a serial cable and it has to be wired a certain way.... (One of my engineers made me up the cable, could probably find the wiring diagram if required, or just use a multi-meter and work out the pin connections from my lead)
